Known issues with watermarking

There are some known issues that apply to the use of watermarking with AMD. Review them before adding this functionality to your property.

Issue Description
There will be a footprint increase when watermarking is enabled Watermarking generates two separate versions of a media file to support its variant A to B switch model. So, storage on your origin will be impacted.
Watermarking can't be applied in Multi-CDN environments This feature will not work as intended in a multi-CDN environment because its functionality is unique to the Akamai CDN. If a request was to be switched mid-stream to another CDN, it would need a version of watermarking that mirrors Akamai's.
Prefetching is not recommended Our current Prefetching implementation uses an origin-assist model that is not optimal with watermarking. As a result, AMD can't properly apply the Segmented Media Streaming - Prefetch behavior and the Watermarking behavior to a single request. Avoid including both behaviors in the same rule. Also, don't apply either behavior in the Default Rule, if the other exists in a subsequent rule in your property. This is because the Default Rule applies to all requests.
Media Services Live is not supported Watermarking is currently only supported for use with on demand media. Your Origin Server 1 must be set to either "Your Origin" or "NetStorage."
Note: If you're applying a Mixed Mode 2 use case for both Media Services Live and other Origin Servers, we recommend that you create a separate rule for your non-Media Services Live requests and include the Watermarking behavior in that rule. Do not include it in the Default Rule because it applies to all requests.
AMD Failover does not work with Watermarking Currently, AMD failover does not work if you also include Watermarking. This should be fixed with an upcoming release.
Range requests are not supported This can cause a range mismatch. Arbitrary range requests are a security violation when requesting a watermarked stream.
